The indoor air quality is much more matter of concern as relative to ambient or outdoor air quality, especially in the context of human health.  However, very few studies have been reported for remediation of indoor ozone by plant species. The main objective of this study is to evaluate ozone deposition velocities and ozone removal effectiveness of three indoor ornamental plant species (Dra...

9 10 Ozone is a major pollutant of indoor air. Many studies have demonstrated the adverse health effect of 11 ozone and the byproducts generated as a result of ozone-initiated reactive chemistry in an indoor 12 environment. This study developed a Computational Fluid Dynamics (CFD) model to predict the ozone 13 distribution in an aircraft cabin. The model was used to simulate the distribution of...

Comment: This manuscript presents a modeling study on the effects of anthropogenic nitrogen deposition on ozone pollution through surface-atmosphere exchanges. The Authors combine GEOS-Chem with CLM to produce an interesting, smart modeling experiment to study several processes (e.g. soil NOx, biogenic VOC, LAI, dry deposition velocity, etc) that affect surface ozone. They find that enhance atm...

Ozone concentration and ecosystem scale fluxes were measured continuously from June 1999 to June 2000 above a ponderosa pine plantation at Blodgett Forest, an Ameriflux site located B75 km northeast of Sacramento, CA (1300m). The ponderosa pine trees were most active during the summer but maintained a low level of activity during the fall, winter, and spring. Cumulative ozone flux for the year ...

A parameterization for the deposition velocity of an ocean-reactive atmospheric gas (such as ozone) is developed. The parameterization is based on integration of the turbulent-molecular transport equation (with a chemical source term) in the ocean. It extends previous work that only considered reactions within the oceanic molecular sublayer. The sensitivity of the ocean-side transport to reacti...

Within the project EUropean Studies on Trace gases and Atmospheric CHemistry as a contribution to Large-scale Biosphere-atmosphere experiment in Amazonia (LBA-EUSTACH), we performed tower-based eddy covariance measurements of O3 flux above an Amazonian primary rain forest at the end of the wet and dry season. Ozone deposition revealed distinct seasonal differences in the magnitude and diel vari...

Dry deposition is an important removal process controlling surface ozone. We examine the representation of this ozone loss mechanism in the Community Earth System Model. We first correct the dry deposition parameterization by coupling the leaf and stomatal vegetation resistances to the leaf area index, an omission which has adversely impacted over a decade of ozone simulations using both the Mo...

To better understand these phenomena,...

A coupled photosynthesis-stomatal conductance model with single-layer sunlit and shaded leaf canopy scaling is implemented and evaluated in a diagnostic box model with the Pleim-Xiu land surface model (PX LSM) and ozone deposition model components taken directly from the meteorology and air quality modeling system—WRF/CMAQ (Weather Research and Forecast model and Community Multiscale Air Qualit...
